CAR-ROOF. i

To all 'wwJ/z it may concern.'

e it known that I, CmN'roN C. MURPHY, a citizen ofthe United States, and a resi- 'dent 'of theclty-of Chicago, in the county ol Cook and State of Illinois, have invented a new and useful Improvement in Car Roofs, of which the following is a specifi cation.

I viis invention relates to outside metal car roofs and particularly to that type of car `roof wherein the roof sheets are arranged for a limited amount of movement on the roof substructure.

' 'One of the principal objects of the invenion is to provide a simple and inexpensive arrangement for securing the roof sheets to thc substrucl ure whereby a limited amount of movement of the roof sheets is permitted so that the sheets may accommodate themselves to the weaving and racking motion of the ear body while in service. A further object is to eliminate the bossing ofthe roof sheets, the extra running board saddles and special pivot bearings now commonly used to impart a pivotal movement to the sheets.

The invention consists in a flashing strip adapted to loosely secure the eaves ends of the roof sheets to the car, said flashing strip having portions on which the eaves ends of the sheets rock. The invention further consists in the parts and in the arrangements and combinations of parts hereinafter more fully described and claimed.'

In the accompanying drawing, which forms a part of this specification and where` in like numerals refer to like parts wherever they occur,

Figure 1 is a plan view of a portion of a roof embodying my invention, parts being broken away to more clearly illustrate the same;

Fig. 2 yis an enlarged vertical section through the eaves portion of the car, the section being taken on the line 2-2 in Fig. 1; y

Fig. 3 is a vertical section eaves portion Vof tht ear on the F ig. 1;

Fig. 4 is avertcal cross-section through in Fig. 1;

through the line 3-3 in and Fig. 5 is a vertical cross-section through the transverse seam on the line 5 5VV Succ-i dcaiion of Letters atent.

Application led Hay 25 191B. Serial No. 236,491.

The roof sheets 6 are loosely arranged on wooden sheathing 7 which `may be supported on any suitable substructure. As shown in the drawings, the substructure comprises side plates 8, side sheathing 9 and facia boards 10. The roof sheets are shown extendinglfrom eaves to ridge on each side of the car and are provided with upstanding flanges 11 and 12 provided with inturned downwardly inclined extremities at their respective side and ridge margins. Bettens 13 extend from eaves to ridge and are nailed or otherwise secured to the roof sheathing between the side flanges of the roof sheets. The side flanges '11 of the sheets on each side of tpe battens are spaced tens and are loosely connected to each other Vby inverted channel-shaped transverse seam covers 14. These4 transverse seam covers have inturned flanges 15, which are hooked under the side flanges l1 of the roof sheets. The ridge ends of the sheets at the ridge and are loosely connected by ridge covers 16 similar to the transverse seam covers 17. These Seam covers are provided with inturned flanges 18, which are hooked under the flanges 12 at the ridge end of the sheets. The ridge ends of the transverse seam covers and the ends of the ridge seam covers are secured 1n position by corner caps 19, which are recessed to receive the seam covers. The eaves ends of the transverse Seam covers are held down at the eaves by angle clips 20. The corner caps 19 are secured to the under roof by bolts, which also secure the running board saddles 21 in position. The running boards 22 are secured to the saddles in any suitable manner. ,The Weight of the running boards and running board saddles is carried by the seam covers and corner caps, sheets free to move under he eaves ends of the roof the seam covers. sheets are turned under and thence downwardly and out-` rIhe eaves flashin 1s provided with strip an lnwardl pro] ecting A flange 26, which projects into t 1e pockets 24 ofthe roof sheets.

The flange 26 of the flashing strip is cut at its inner edge into away from the bat-Y thus leaving theV are spaced apart segments of eireles forming a scalloped edge portion, which is adapted to beur against the inner wall of the pockets 2J: formed 0n the under side of the roof sheet. The relution between the scalloped edge of the Hush ing strip and the inner wall ot' the pocket 24 of the root' sheets is surh that the eonvex or rounded lobe portion 27 forinedby sealloping the edge ot' the llunge 26 oi the Hush ing strip is closest to the inner wall ot' the grooves "24 of the roof. sheets at their eenters. This arrangement permits the sheets to rock or roll on the lobe portions 27 of the flashing strip, thereby accommodating themselves to the vnrious` distortions of the car substructure.

The foregoing described arrangement is Considered onliy as :in example and as the one best suited to the type of roof shown. There fore., I do not ivish to be limited to the torni ot' seam shown.y as the invention is also :ip- )lieable to roofs having various forms of flexible seams.

flint IA claim :is in v invention is:

l. A cnr ro'of comprising roof sheets movably mounted on the substructure, said sheets having grooves formed in their envesis ends, and n st rip secured to the eaves of the` ear and arranged to project into said grooves, the edge portion of the strip which proJect's into the grooves fornied in the roof sheet being spaced from the bottoms of said grooves at different distances.

2. A ear root comprising roof sheets movnbly mounted on the substrueture,said sheets having grooves formed in their eaves ends, and means engaging said grooves t'or loosely securing the eaves endsl` of the roof sheets to the cnr sulistrnrture, said ineens approach ing the bottoni ot' .said grooves more closely at the center ot' the sheets than :it their side margins.

3. A car root' eornprisin roof sheets extending from eaves to ri ge on euch side of' the eur, said sheets having rooves in the eaves ends und being connecter? to each other by loose joints at the side and ridge mal'- gins, und :t continuous angle strip loeuted ntl the eaves of the ein', one of the le of sind angle strip being secured to the Sise of the ear and the other ot said legs being nrranged to project into the grooves of a number ol' root sheets, theedge ot' said last mentioned leg ot' the angle strip being scello ed, whereby the lobes formed by the seal ops are closest to the bottom of the grooves formed in the sheets midway between the side trial-gills of the sheets.

l. eur rootv eon'lplising a plurality 0f root' sheets flexibly connected at the side margins, .said sheets havingr continuous ,grooves toi-ined in the under sides at the eaves ends, and angle strips secured to the eaves` ends ot' the car, said angle strip having iinvzirdl)v projecting portions extending into the grooves formed in said sheets, the edges nl' .said inivardlbY projecting portions being srallnped. t

5. A, ear root" comprising roof sheets flexibl)Y serured to each other at their side murgins. the eaves ends ol suid sheets being rebent inuardljv` und thence outwardly to form grooves in the eaves edges, and an angle strip havingl one leg secured to the our body, the other leg of said strip being arranged to projet-t into the grooves in said sheets, the marginal edge ot' sind leg being scalloped andai-ranged so as to bring the convex portion ot the ,scalloped edge closest to the bottoni ot' the root' sheet rrooves midway of the side margins of the s Bets.
